Specification of Letters Patent.

I iPatented an? 251 To all whom it may concern:

Be it known that I, JOHN B. CAR Y, a

citizen of the United States, and a resident of Roslyn, in the county of Nassau and State ofNeW York, have invented a newand Improved Stone-Boat, of which the following is a full, clear, and exact description.

This invention relates to certain improve- ,ments in drags or stone boats ada ted for dropped to permit the material to slide therefrom. The invention consists in the construction and arrangement of parts set forth m the claims and one form of which is hereinafter described.

Referenceis to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures, and in which Figure l is a top plan View of an apparatus constructed in accordance with my invention; Fig. 2 a side view thereof with the platform supported in a horizontal position; and l 3 is a side elevation with the platform in an inclined or dumped position.

in the specific form shown my improved stone boat or sled includes a platform 10, constructed in any suitable manner and adapted to s'ceport a load of stone, dirt or any .eriel which it is desired to transport. rive platform may be reinforced,

braced strengthened in any suitable mannor, but as the specific construction of the platform so does not involve the present invention, no such reinforcement or bracing means is shown. Tl c platform is supported by two side members or rumiers 11 of substantially the same length as the platform, and having their front end portion 12 inclined upwardly to facilitate the passage of the runners over uneven ground. The platform is connected to the runners and suptwo lower sections 17', ll".

ported thereby, so as to be movable to either a horizontal position or an inclined :position. This supporting means, as shown, includes two standards 13 and 14, spaced apart and connected to the'under side oftheplatform at points approximately one-third the length of the platform from each end. The standard or support 13 is rigidly braced to the runner and is connected, to the under side of the platform by a pivot- 15. The 'rear standard or support is formed of tw'o sections 16 and 17, having their ends normally abutting and connected by a hinge 18. The upper end of the upper section 16 is secured to the under side of the platform by a pivot 19, and the lower end of the, lower section is connected to the runner by apivot 20.. The two sections thus constitute a toggle joint, and when in alinement are of such length that the platform is supported substantially horizontally. lVith the platform in a horizontal position, as indicatedinhig. 2,.the front end thereof rests upon a shoulder or seat 21 at the front end of the runners, while the rear end of the platform is unsupported. Viith the load evenly distributed fuponvthe platform, there will he no tendency of the platform to tip or tilt, and the presence of the driverupon the front end of the platform will additionally prevent any such tilting.

For duu'lping the load from tho-platform, I provide means forbreaking the toggle joint and lowering the rear cndof the platform, so that said platform will assume an inclined position, as indicated in. Fig. Various different forms of operating means may be employed for breakingtheltogglc, hut shown, I connect the'two toggles by two transve rods 211- and 23. are subs;

connec standa 4 to .h standard, wh .i

These rods parallel and one of them 3 "tion 16 of one rear se'tion 16 of the other vwond rod connects the To break the toggle, these two rods are forced rcarwardly by -means of two opfating rods 24 and 25, which extend torw. dly bemalh the platform and JIZ ct to the lower end of a handle lever This lever extends substan tially verti ,ally at the front end of the platform, and is fulcrumed upon a rod 2'? eX- tending across\ from the upper end of one runner to the upper end of the other. The upper eud'of the handle is directly in front of the driver on the load, and may readily be operated when it is desired to dump t ing any jolting or jarring of the apparat: in passing over very rough or ground.

\Vhen the platform is dumped, it tilts upon 1 the frontpivot 15 and the front end rises, while the rear end drops. the rear end of the platform in its lowered position, I may provide stops 28 upon the runners adjacent their rear ends and presenting upper inclined surfaces to coincide with the inclined under surface of the lower platform. If desired, the two stops 28 may beconnected by a transverse b 'ace 29 extending from one rinuir to the other and supporting the platform across its entire width when said platform is in dumping position.

Having thus described my invention, claim as new and desire to secure by Letters Patent:

1. In combination, two runners having upwardly-turned front ends, a platform ing thefront end thereof adapted to enga e with the upturned front ends of the runner x, standardsnnounted on said runners and pivotally secured to the platform in front the center of gravity of the latter. stan ards mounted on said runners in the r of the first-mentioned standards and adapt t to support said platform in the rear of th center of gravity of the latter, said last mentioned standards including toggle joints which when broken permit the res r end oi the platform to move downwardly, and stops upon the rear ends of the runners for limiting the downward movement of the rear jr v- For-supporting .en in .o'vered position.

n combination, two runners having d front ends, a platform hav- 1nd thereof adapted to engage turned front ends of the runners,

noted on said runners and ivecured to the platform in front ot the gravity of the latter, and stand- .utet on said runners in the rear of 'entioned standards and ada ted latform in the rear 0 the of the latter, said last-menincluding toggle joints lten permit the rear end of g to move downwardly.

n combination, two runners, a platstandards mounted on said runners ecured to the Iatter at a re the front end and the 'orm, standards carried by the rear of said first-menand pivot-ally secured to inter iediate the rear end of and lhc center of the platform, 1 "ed standards including two sections, the pivotal movable rearwardl to permit the rear end of t e platform,

lever pivoted adjaends of the runners, and

said lever below the pivlatter and to said secondids. whereby when the upover is moved forwardly, the pla =orm islowered.

whereof I have signed my the platform and supporting the lat u wont JOHN B. CAREY.
